Booting in Tethered Mode
As we know currently there is no untethered jailbreak available for iOS 4.3.2 so you have to boot it into a tethered jailbroken state. For this you will have to use “tetheredboot” by following the steps posted below.
STEP 12. First you have to download tetheredboot.zip utility for Mac OS X then you have to extract the .zip file.

Now you have to change the extension of the original iOS 4.3.2 file from .ipsw to .zip. and then you have to extract this .zip file.
Now you have to copy kernelcache.release.n90 file, and then you have to copy iBSS.n90ap.RELEASE.dfu files, you can find these files under /Firmware/dfu/.
Now you have to create a new folder named “tetheredboot” on the desktop and then move all the two files and tetheredboot utility to this folder as shown in the image below:
STEP 14. Simply turn off your iOS device, then start Terminal on OS X and run the commands given below:
sudo -s
Now simply enter your administrator password, then:
/Users/Max/Downloads/tetheredboot/tetheredboot
/Users/Max/Downloads/tetheredboot/iBSS.n90ap.RELEASE.dfu
/Users/Max/Downloads/tetheredboot/kernelcache.release.n90
You should note that you will have to replace “Max” with the name of the directory on your computer.
If the above command fails then you can try ‘tetheredboot -i ibss -k kernel’ instead of ‘tetheredboot ibss kernel’:
/Users/Max/Downloads/tetheredboot/tetheredboot –i
/Users/Max/Downloads/tetheredboot/iBSS.n90ap.RELEASE.dfu -k
/Users/Max/Downloads/tetheredboot/kernelcache.release.n90
Now you will be asked to enter DFU mode. Now simply follow the steps posted below to enter DFU mode:
- Hold down both the Home and Power button for ten seconds.
- Now release Power button but keep holding the Home button for ten more seconds.
- Now your iOS device should be in DFU mode.
Now you have to wait until your iOS device boot. At this time you will see “Exiting libpois0n” message at Terminal. After some time your iOS device will be booted in a jailbroken tethered mode. In this way you can jailbreak iPhone 4 on iOS 4.3.2 using PwnageTool 4.3. [Via]
